Most CPG brands manage Amazon EU like a traditional key account. Amazon requires something different: continuous, data-driven, cross-functional decisions. The org chart is the root cause of underperformance — not the channel, not the team, not the agency. The brands compounding on Amazon EU changed the operating model. Everyone else keeps optimizing tactics inside a broken structure.
Anyone who's worked inside CPG has sat in that meeting.
The quarterly Amazon review. Results flat, or down. Someone on the brand side asks why the media investment isn't converting. Someone on the trade side explains that the promotional calendar was misaligned. The category manager says the content needs updating. The Amazon KAM nods and talks about organic ranking.
Nothing gets decided. The budget gets reviewed. Amazon gets blamed.
The channel isn't the problem. The channel is performing exactly as it was set up to perform.
That's the problem.
What "running Amazon like a key account" actually looks like
Most big CPG companies manage Amazon the same way they manage Carrefour or Walmart: quarterly JBP reviews, annual content refreshes, trade budgets negotiated in isolation from media spend, brand P&L owners who barely track Amazon as a line item.
The behaviors are specific. A KAM team negotiating trade terms without visibility into retail media ROI. Content treated as a one-time creative project that goes live and stays untouched for 18 months. Promotional planning built around the brand's marketing calendar, not Amazon's demand curve. Media budgets sitting in a digital team that doesn't talk to the account management team that doesn't talk to the supply chain team that's the reason the Prime Day promotion failed.
This is normal. This is how most large CPG organizations run Amazon in Europe. And it produces predictable results: tactical wins that don't compound, performance that plateaus, and a persistent feeling that Amazon "should be doing better" without clarity on why it isn't.
The org chart is the root cause
Amazon EU doesn't fit neatly into a CPG org structure. That's the actual problem.
In most large CPGs, Amazon sits somewhere uncomfortable: under a country GM who has a dozen other priorities, or under a pan-EU KAM team with no brand authority, or under an eCommerce vertical that's treated as a separate channel rather than an integrated commercial system. Sometimes all three, depending on the market.
None of these structures are built for how Amazon actually requires decisions to be made: fast, data-driven, cross-functional, continuous. Amazon's algorithm doesn't wait for the quarterly review. The conversion rate on a PDP changes overnight. A competitor's promo event reshapes category share in 72 hours. The window on a trending search term opens and closes before most approval processes are finished.
Category thinking produces category results. Amazon rewards something different.
What Amazon actually rewards
This is the pivot point.
Amazon rewards systems fluency. The ability to see how an AMC cohort analysis changes a promo decision, which changes a retail media allocation, which changes a content priority, which feeds back into the next AMC cycle. Not isolated tactics executed against a plan. A flywheel — and a team organized to spin it.
The AMC data tells you that your top-spending customers also buy from a competitor after their third purchase. That's not an Amazon problem. That changes your promo architecture. Which changes your JBP negotiation. Which changes what you ask your content team to prioritize. Four departments. One data point. Most corporate CPG structures can't make that connection in a single meeting, let alone act on it in a week.
The brands compounding on Amazon EU have internalized this. They don't run Amazon as a checklist. They run it as a live system where every signal connects to a decision.
The EU amplifier
Every structural problem that exists in the US becomes a failure mode in Europe.
Multi-country complexity is the obvious one — DE, UK, FR, IT, ES operating with different category dynamics, different regulatory environments, different localization requirements, and critically, different country-level P&Ls with misaligned incentives. What works as a promotional mechanic in Germany has different margin implications in France. A content asset built for the UK market requires legal review before it goes live in Italy. And the country GM in Spain, who is accountable to a different set of stakeholders than the pan-EU eCommerce team, isn't especially motivated to coordinate.
Speed dies in this structure. And on Amazon EU, speed is the lever.
The US market has the same organizational challenges, but the single-market reality compresses them. In EU, complexity multiplies at every layer. A strategic misalignment that costs you 2% of performance in the US costs you 8% in Europe, because it fails in four countries simultaneously for four different reasons.
What the winning brands are doing differently
It's not what you'd expect. The answer isn't "hire more Amazon specialists."
The brands actually compounding on Amazon EU have made one of two structural choices:
The first: a real Amazon P&L with cross-functional authority. Media, trade, content, and data sitting under a single accountability structure — not dotted lines, not a steering committee, not a monthly alignment call. One P&L. One decision-maker with authority over all the inputs.
The second: a senior operator who speaks both languages. Someone who understands Amazon's mechanics at a technical level and can translate them into the language that gets decisions made inside a corporate structure — JBP negotiations, brand investment cases, category strategies. Someone who doesn't need to escalate every cross-functional call because they've been given the mandate to move.
The lever is structural. The tactics are downstream.
The JBP trap
The annual JBP process is where this plays out most visibly.
Most brands approach the JBP as a commercial negotiation: trade terms, promotional support, content shelf commitments. They negotiate what Amazon will give them and what they'll give Amazon in return. The deal gets signed. The year starts. Three months later, nothing is tracking the way the JBP assumed it would, and no one has the authority to change the operating conditions mid-year.
The brands winning on Amazon EU use the JBP differently. They treat it as a structural alignment document — and they use it to lock in the operating conditions that let the flywheel spin. Data access terms. Content update SLAs. Co-op structures tied to performance triggers, not static commitments. The question going into the JBP isn't "how much promotional support can we get?" It's "what operating model are we agreeing to?"
Most JBP conversations are about trade terms. The best ones are about operating model. The difference compounds over time.
The retail media misallocation
One more specific illustration, because it's where the most money is being left on the table.
Most CPG brands on Amazon EU run retail media as a performance channel. They measure ROAS. They optimize Sponsored Products campaigns against conversion. They set a target ACoS and manage to it.
The brands winning aren't measuring retail media in isolation. They're using it as a demand signal — reading what's converting at what cost, understanding what's driving traffic that isn't converting, and feeding that back into commercial decisions. A keyword with high click-through and low conversion is a content or pricing problem, not a bid problem. A Sponsored Brand campaign outperforming a category search tells you something about your brand relevance in that moment that should change your JBP priorities.
Same spend. Completely different strategic posture. One is optimizing an input. The other is running a system.
What to do if you're inside the machine
Most operators reading this can't restructure the org tomorrow. That doesn't mean there's nothing to do.
Three things you can move on this week:
Build the flywheel logic internally, even if the org doesn't require it. Document how your decisions connect. Show your leadership how an AMC insight changes a promo decision which changes a media allocation. Make the system visible. Most senior leaders haven't seen it mapped — they'll respond to it.
Find one metric that crosses functions and make it the team's north star. Share of wallet on your top SKU. New-to-brand customer rate. Repeat purchase rate by cohort. One number that forces the brand team, the media team, and the trade team to sit in the same room and own the same outcome.
Use your JBP to get the operating conditions that matter. Don't negotiate only for trade terms. Negotiate for the data access, the content SLAs, the co-op flexibility that gives you the ability to respond fast. That's where the real leverage is.
The question worth asking
The question most Amazon teams are asking: "How do we improve our Amazon performance?"
The question that actually matters: "Are we organized to let Amazon compound?"
Those are different questions. They have different answers. The first produces optimizations. The second produces structural change.
If your org is built for category thinking and you're running Amazon against a quarterly plan, you'll keep improving tactically and losing strategically. The brands that are compounding on Amazon EU didn't find a better tactic. They changed the operating model.
The channel is performing exactly as it was set up to perform.
Build the right setup.
